Professor David Reay graduated from Bristol University in Aeronautical Engineering in 1965. He currently works part-time as a Senior Research Associate as PI on a Carbon Capture project funded by EPSRC at Newcastle University and is an Honorary Professor at Nottingham University and a Visiting Professor at Northumbria University, Newcastle. He has about 50 years of experience of process energy efficiency activities, covering heat recovery, heat pumps, heat pipes, and process intensification.  He co-ordinates both HEXAG (Heat Exchanger Action Group) and PIN (Process Intensification Network) – networks respectively running for 20 and 12 years. He is Founding Editor of Applied Thermal Engineering and is Editor of a new Elsevier Journal – Thermal Science and Engineering Progress.  Professor Reay has advised the UK Energy Efficiency Programmes and the EC Energy R&D and Demonstration programmes over many years, with an emphasis on thermal processes. His main task is as Principal Consultant of David Reay & Associates (DRA), which has been active in consulting engineering since 1987. Prior to that, he worked in aerospace and at International Research and Development Company in Newcastle on heat transfer and fluid flow problems in nuclear reactors. Professor Reay has completed via his Consulting Engineering business, with Professor Colin Ramshaw, studies for Alstom Power on (i) heat exchanger technology trends for carbon capture, and (ii) preliminary sizing and costing of an intensified absorber for a post-combustion carbon capture plant.
